England captain Chris Robshaw described last week's loss to Wales as 'devastating' but claims it has now brought the players closer together.
Rugby World Cup co-hosts England face Australia at Twickenham on Saturday and will be looking to redeem themselves after their heartbreaking 28-25 loss to neighbours Wales last week.
England were seven points ahead with 10 minutes to play in London but a converted try and a penalty saw them trail by three late in the game.
Stuart Lancaster's men had the chance to level the scores at the death but the decision to go for the win instead did not pay off.
"You have to take the rough with the smooth. There are good times, there are bad times and you need to learn how to deal with it," Robshaw said.
"You need to know what's happening, absorb it and use it. That's the best way. You want to go out and prove a couple of people wrong.
"As a team it brings you closer together. You find out about the character of the individuals around you, how much you mean to each other and how much people outside mean to you.
"That's when you really see a team form, there's a unity in it. We've got ourselves in the best possible frame of mind to deliver and now we need to."
A win for England against the Wallabies is vital if they are to keep their chances of progressing in the tournament alive.
If they lose they will become the first hosts in World Cup history to fail to reach the quarter-finals of the showpiece tournament.
"We have an option. We can change things this weekend or we can let it linger," Robshaw added. "As players we have to front up and change things. There is no point dwelling on it.
"Last weekend was heartbreaking and devastating. We let things get away from us, but in sport a week can be a long time. We have got that chance on Saturday to put it right.
"It's knock-out rugby. There's no second chance. It's all on the line. We know that."
